Beamline 3 is home to the Facility for Irradiance Calibration Using Synchrotrons (FICUS). FICUS takes advantage of the calculability of synchrotron radiation. The beamline is used to calibrate the absolute spectral irradiance of ultraviolet light sources like deuterium lamps.
Calibrated deuterium lamps are available through the NIST Calibration Program.
Specifications / Capabilities:
Spectral range 200 nm to 400 nm
